Abstract
In a paper presented at the 1977 Particle Accelerator Conference, R. Faulkner and R. Cooper outlined the design of the LAMPF Line D Fast Kicker System. At that time the prototype had been constructed and initial tests were complete. After the Kicker was reassembled in final operating configuration, some components were extensively modified, and considerable operational experience has since been obtained. The system has now operated in production for over 500 hours. The modifications made to the original design were few but important in terms of reaching the system design objectives. Much of the continuing component development program has centered on upgrading reliability at sustained high average power levels. The Kicker is presently capable of delivering 7-μs-long pulses at a 120-Hz repetition rate with a peak current of 5800 A. It has operated for complete LAMPF prodtuction cycles without maintenance. Continued development work has concentrated on the high power load resistor, the pulse forming network (PFN) capacitor bank, the charging inductor, and the elimination of component failure caused by high voltage/current discharges. This paper discusses Kicker problem areas and solutions.
